bathtub to thestack below the point where the drain from the closet discharges into the stack, so that the drain from the closet will flush the discharge openings from lavatory, and bath-tub and carry ofi foreign matter, such as -.lint, dirt, string and matches. In many instances, horizontal runs of pipe are necessary between the stack and the closet, lavatory and the bath-tub, respectively and it is desirable to confine these pipes between the joists in-the floors,

so that they will not protrude and render them.

The present invention designs to provide an improved T-fitting in which the inlet openings of the stack-pipe are horizontally alined to permit the horizontal runs of pipe to be disposed side by side between the floor and in which provision is made for dis-i charging the drain from the bath-tub tor lavatory into the stack-pipe below thepoi'nt where the drain from the closet is dis charged into the stack.

The invention further consists in the several novel features hereinafter set forth and more; particularly defined by claim at the conclusion "hereof.

" Inthe'drawings: Figure 1 is an end elevation of the fitting. Fig. 2 is a side elevation thereof. Fig. 3 is a top plan view of the fitting. Fig-. 4; is a section taken on line l-tof Fig. 1, Fig. 5 is a section taken on linej55 of Figui.

The fitting 9 is cast in one piece and comprises a main pipe 10, which is connected to the stackin'the drainage system at its .ends 11 and 12 and forms a part thereof,

and inlet pipes 13, 14 and'15. Inlet pipe Specification of Letters Patent. i I

By disposing the discharge openings 18 and 19' below the discharge opening16 the passagesin pipes 14 and 15 are gradually curved to dir ectth drainage I and longitudinally o the stack instead of discharging it directly against the wall thereof.

The invention thus proved one-piece T-fittingwhich includes connections for pipes disposed side by side and in which the-passages are directed. to

effectively prevent clogging.
